Marine Holding Tanks

Marine holding tanks are used for holding black water and grey water in boats, yachts, and sailboats. They are BPA free and rotationally molded with FDA approved polyethylene resin for potable water. Boat holding tanks are created by American manufacturer’s Ronco and Dura-Cast. Their rotationally molded design makes them crack resistant, durable, and long-lasting.

Capacities range from 5 gallons to 202 gallons, with thicknesses of 0.1875 inches (3/16") to 0.375 inches (3/8"). Both standard rectangular tanks and custom-molded tanks are available with pre-installed fittings or an optional DIY fittings package if buying a blank tank.

These holding tanks are new and can be used as replacement or new additions to vessels. They are designated for grey water or black water usage and should not be interchanged for potable water purposes.
